Description:

Abstract: This layer shows only the rocky features from the interim Surficial Geologic Habitat Map v.3.6.1 for the Territorial Sea, used in the TSP process.
Purpose:
These data were originally developed to support the identification and delineation of Essential Fish Habitat (EFH) for west coast groundfish. Subsequently, they have been revised through hand interpretation in support of Oregon's efforts to impliment Marine Reserves within the Territorial Sea.
Supplemental Information: These data repressent an interim product between the smoothsheet data (Version 3) and a subsequent, science-grade, interpretation of the data which will constitute a Version 4 revision to the map.

Overview Description:

Entity and Attribute Overview:
The data presented in this shapefile was modified from the original source (Versions 1 & 2; Romsos 2004, Romsos 2007 and Version 3.0; Agapito 2008) to it's current form Version 3.5.
Interpretation Changes:

This Version 3.5 product represents a significant revision to earlier SGH maps for Oregon. The most significant change is the hand digitization of habitat types in the vicinity of pilot and proposed marine reserves within Oregon's territorial sea (generally, the first 3 nm from the beach). This revision was completed through visual interpretation of both bathymetric and backscatter and ground truth data collected subsequent to the release of the Version 3.0 map.

The remainder of this section is with regard to the steps taken during the completion of the Version 3.0 map:

Version 3.0 interpretation is detailed in Melinda Agapito's MS Thesis (2008, College of Oceanic and Atmospheric Science, Oregon State University, Corvallis, OR 97331). In brief, the new territorial sea mapping followed a compatible interpretation method but utilized previously unknown and unavailable historic data from the U.S. Office of Coast and Geodetic Survey (Now the National Ocean Service).

Version 2.0 Attribute Table Changes Include:

(1) The addition of a second SGH habitat attribute class, "GEO_HAB2", which is identical to the "GEO_HAB" attribute code in most cases except where a Version 1 or 2 polygon falls within the areas: (1) remaped by Lanier (previously unpublished data and Lanier 2006 MS Thesis), or (2) within the Territorial Sea of Oregon (Cmpletely remapped for Version3). Again, the original classification coding from Version 1 or 2 is retained in the "GEO_HAB" attribute field and polygons that have been remaped and recoded, by Lanier, are denoted with an asterisk (*) after the GEO_HAB attribute code. Territorial Sea polygons have a "NA" GEO_HAB attribute because the new mapping superceeds the old mapping. The new code is a more detailed interpretation of Simrad em300 multibeam bathymetry and backscatter data on the northern Oregon outer continental shelf and upper slope. The Greene et al. 2005 classification scheme was modified slightly to fit our interpretation of the data.

Example:

GEO_HAB = She* -- Original Version 1 or 2 habitat polygon attribute coding, * denotes a remaping occured
GEO_HAB2 = She/s_d -- Updated habitat polygon attribute code after remaping.

What this means: The original maps (Versions 1 & 2) classified this polygon as rocky shelf. Subsequent mapping with additional data reveals something more about the composition of this polygon (see Overview citation code descriptions). It's still a rocky shelf habitat so the "GEO_HAB" code remains valid. the GEO_HAB2 provides the enhanced classification. Both attribute fields are kept because we can't enhance every polygon in the map until the appropriate data is collected at which point the "GEO_HAB" attribute field will become deprecated.

(2) We have added 3 new attribute fields (SGH_prefix, SGH_lith1, and SGH_lith2) These attributes fields are included to provide a more accurate cross-database mapping of seafloor habitats to species habitat preferences. More specifically, this dataset is bieng developed in harmony with the NOAA Fisheries NWFSC Habitat Use Database of HUD (a collection of habitat prefrences by species and lifestage for westcoast groundfish). We found the Version 1 and 2 "Geo_Hab" attribute codes (after Greene et. al) difficult to map to the HUD which uses a slightly different habitat classification scheme. Most simply, we've simplified the "Geo_Hab" attribute code into a 2 character code we call "SGH_prefix" without losing any information that is useful for identifying species-habitat relationships from the HUD database.

"SGH_lith1" and "SGH_lith2" represent the primary and secondary surficial lithologic or sedimentary characteristics of the polygon. This means that "SGH_lith1" is our best estimate of whats most abundant in the polygon and "SGH_lith2" is what follows that in abundance. In most cases we've no means to quantitaively measure lithologic or sedementary composition, therefore the vast majority of polygons only include a primary lithology.

Version 3.5 Attribute Table Changes Include:

GeoHab2 attribute field was dropped for Version 3.5 because it was not maintianed well and we do not have confidence that it represented anything meaningful anymore.
